1. A visualized image display device comprising:
a memory containing program instructions; and
a processor coupled to the memory, wherein the processor is configured to execute the program instructions to:
acquire time-series feature data in which time-series data of a feature of an object in a video and an object ID are associated with each other, and classification data in which the object ID and a class ID labeled to the object are associated with each other;
select a class ID to be visualized;
acquire the object ID associated with the selected class ID from the classification data, acquire time-series data associated with the acquired object ID from the time-series feature data, and on a basis of the acquired time-series data, display a feature image representing a temporal change of the feature of the object having the selected class ID, on a display device; and
select variables from among a feature amount type, elapsed time, a class, and an object, the selected variables to be assigned to hue (H), saturation (S), lightness (V), and transmittance (alpha) of a display element shown on a horizontal axis and a vertical axis of a coordinate plane on which a visualized image is shown, wherein the variables to be selected are shown on the coordinate plane.
